Abstract

Liposomes are spherical vesicles composed of one or more phospholipid bilayers that have gained prominence in cosmetic formulations for their ability to enhance the delivery of active ingredients into the skin. They encapsulate various hydrophilic and lipophilic compounds, protecting these ingredients from degradation while increasing their bioavailability and stability. This encapsulation allows for controlled release and targeted delivery, which improves the efficacy of active agents such as vitamins, peptides, and antioxidants. In cosmetics, liposomes are used to improve skin hydration, reduce signs of aging, and support skin barrier repair. Advances in liposome technology, including nano-liposomes and multilamellar liposomes, have further expanded their applications, enabling better penetration and prolonged release times. This abstract summarizes the utility of liposomes in cosmetics, their structural advantages, and their impact on skin health and product performance.
